In electromagnetic induction, the induced E.M.F is independent of
- A. Change of flux
- B. Time
- C. Tesla
- D. weber
Step-by-step solution
Faraday's law states that induced emf is proportional to the rate of change of magnetic flux. Therefore, it depends on the change in flux (option A) and the time taken (option B). The unit 'tesla' (option C) is for magnetic field, which can affect flux if changed, but the induced emf is independent of the absolute value of magnetic flux itself, measured in weber (option D). Thus, the correct choice is D.
